Soils are full of life - and not just in the form of plants. Bacteria, archaea, and fungi affect organic matter decomposition, plant growth, and nutrient cycling, to name just a few essential processes. These extraordinarily diverse microbial communities are largely unseen, but control many of the processes that we care about. What is the extent of microbes in soils and is their diversity important for soil health? How do they respond to organic matter additions? Is it possible to manage them? We will address these questions in the context of manure management.

Dr. Thea Whitman is an assistant professor in the Department of Soil Science at the University of Wisconsin-Madison. She earned her Ph.D. at Cornell University, and is from Nova Scotia, Canada. Her lab studies soil microbial ecology and biogeochemistry, with an emphasis on organic matter cycling in soils.

Managing manure and nutrients on tile drained lands while protecting water quality can be a challenge.

Winter in Wisconsin is the reality for several months out of the year. However, weather conditions are not uniform throughout the winter. Knowing how to manage manure through variations in early and late winter weather is critical for environmental sustainability and fertility management. There are new elements of state and federal regulations that may impact your management decisions. UW Discovery Farms data has zeroed in on manure management strategies that are easy to implement that will protect water resources and production goals from harm during those frosty months.

On-farm research plots were completed in Ohio using liquid swine, liquid dairy, and liquid beef manure to provide sidedress nitrogen to emerged corn. A 5,250 gallon Balzer manure tanker and Dietrich toolbar were used to incorporate manure into corn at the V3 stage and compared to similar amounts of sidedress nitrogen in the form of 28% Urea Ammonium Nitrate in more than 45 replicated plots over five years. Yield results were similar when comparing the corn sidedressed with manure to the corn sidedressed with commercial fertilizer. Using liquid livestock manure with growing crops can capture more of the manure nutrients and reduce the need for purchased fertilizer.

Glen Arnold is an Associate Professor with Ohio State University Extension and serves as a Field Specialists in the area of Manure Nutrient Management Application. His on-farm research focuses on the use of livestock manure as a spring topdress fertilizer on wheat and as a sidedress fertilizer for corn. His research goal is to move livestock producers toward applying manure during the crop growing season instead of late fall application window. His more recent research has focused on sidedressing emerged corn with a soft drag hose system.

A drag hose and manure incorporation toolbar was used to sidedress emerged corn with swine finishing manure at the V2 to V3 stages of growth for three crop seasons in Darke County, Ohio. The corn sidedressed with manure out yielded the corn sidedressed with 28% urea ammonium nitrate by 13 bushels per acre. The manure application rate was 6,500 gallons per acre and contained the same amount of available nitrogen as the commercial fertilizer used. The use of liquid manure to sidedress corn can provide a new window of time for manure application in Ohio and apply manure when a growing crop could utilize the nutrients.

The majority of the nutrient management planning in Wisconsin for farms of all sizes and types is done with SnapPlus nutrient management planning software. Developed at the University of Wisconsin with support from state agencies and NRCS and first introduced in 2006, it is freely available. The software keeps field-by-field records of crop nutrient needs and planned and completed manure and fertilizer applications. It helps producers follow the standards and guidelines relevant to their operation when planning manure applications. It includes a web-based mapping component that allows farmers to map where on their fields they can spread manure.

James Beaudoin has been creating online GIS applications for more than 15 years. Most of those years were spent with the Applied Population Lab developing tools to help people use and understand U.S. census data. Presently he works for UW Soil Science creating tools that help farmers, consultants, and agronomists create nutrient management plans that meet the Wisconsin 590 and NR 243 standards. He tends to use open source technologies over proprietary software. He is interested in making GIS easy for non-professional GIS folks and creating tools that help to visually display data in way that help users make better decisions based on patterns and relationships in the data.

Sarah Sebrosky is a programmer analyst for SnapPlus, Wisconsin’s nutrient management planning software. She has mastered reporting, field grouping, and a number of SnapPlus’ other wonderful features.

Uniformity of liquid manure application across the tool-bar points is important to ensure proper nutrient supply for crop growth, to maintain producer confidence in nutrient availability, and for addressing water quality concerns. In this project, six commercially-available, tank mounted manifolds for liquid manure distribution were tested for coefficient of variation. Testing was performed using water and coefficients of variation were determined for application rates ranging from 2000 to 8000 gallons per acre. Tests were performed under three different slope conditions of 0, 3, and 6 percent to simulate cross-slope manure application. Coefficient of variation, calculated for the average application rate as measured across the tool-bar, was less than 20 percent for three of the six manifolds tested for the five application rates for all three slope settings. Results of the testing indicate that caution should be exercised to select the appropriate manifold when applying manure such that the lowest possible coefficient of variation is achieved.

Dan Andersen is an Assistant Professor at Iowa State University. His research and extension work focuses on developing and promoting methods that help farmers better utilize their manure. He works on topics ranging from anaerobic digestion, nutrient separation, and the economics of manure utilization. He grew up on a dairy farm and is passionate about promoting practices and knowledge about manure. You can follow him on Twitter @drmanure.

The perspective of whether manure is a waste or resource is often based on the perception of if the cost to utilize (transport and land apply) the manure as a fertilizer is more or less expensive than purchasing commercial, mineral fertilizers. One method that has been proposed for improving the transportability of manures is to perform a treatment where nutrient enriched and nutrient depleted fractions are created. In this work, information on how different manure nutrient partitioning strategies of differing effectiveness would impact the costs of manure application was evaluated. This analysis provides information on the amount of money an operation could potentially put towards implementing the manure treatment technology as it must be equal to or less than the reduction in manure application costs to be an economically viable option.

Wisconsin’s nutrient management planning software, SnapPlus, contains field-scale models for erosion (RUSLE2) and runoff phosphorus (Wisconsin P Index). Farms throughout the state routinely use the software and it provides a powerful tool for producers to examine how they can reduce sediment and phosphorus losses from their own fields. Agricultural watershed projects use it for locating fields needing conservation efforts. This software also has adaptations to support water quality trading programs.

Laura Ward Good is a soil scientist and the lead developer of the Wisconsin P Index, a model for quantifying the risk of runoff phosphorus losses from cropland. She has worked with integrating the P Index and erosion estimates into SnapPlus nutrient management planning software SnapPlus in the UW Madison Soil Science Department since the software project began in 2003. Her goal is to make sure the software can be used and understood by everyone who does farm nutrient management planning in Wisconsin.

Manure supplies secondary and micronutrients. There is an increasing interest in knowing the approximate secondary and micronutrient content of dairy manure. From 2013 - 2015, the UW-Extension Nutrient Management Team funded testing of 300 randomly selected dairy manure samples. The samples were tested for total amount of secondary and micronutrient content. Liquid manure samples were characterized as having a dry matter (DM) content less than or equal to 11%. Samples with more than 11% DM were considered solid manure. Of the 300 manure samples, 195 were liquid and 105 were solid. This presentation will cover the results of the three year survey and the value of the secondary and micronutrients that are applied in a normal manure application. The result is the probability of farmers not required to purchase secondary or micronutrients with normal dairy manure application.

Richard with other county colleagues and UW-Extension specialists provides research-based information to educate farmers and residents in Clark County, WI. His focus is the crediting of available farm nutrients to reduce input cost to provide profitable crop production. Farmers crediting available farm nutrients will contribute to the sustainability of the farm along and potentially improve soil and water quality in Clark County WI. Richard received his BS from UW-River Falls in Broad Area Agriculture, a MS in Agronomy from Iowa State University, and is a Certified Crop Advisor with over eighteen years of work experience in agronomy.
